Title:
  Grub update fails on zfs root drives after software install..

Status in grub2 package in Ubuntu:
  Incomplete
Status in grub2 source package in Focal:
  Incomplete

Bug description:
  My grub.cfg file first menu entry works.  Used to refer to specific
  hard drives which will not work with ZFS root devices.

  It also loops and adds another "}" at line 183.

  Memtest again refers to /dev/sd<x> which I don't think will work with
  ZFS filesystems?

  See the two files attached.

  grub.cfg I modified to make it work to see first menu entry or
  linux*88 menu entry.

  The second one is the generated grub.cfg.new which is bad.
